Introduction to Alumina Ceramics

Alumina ceramics are known for their high hardness, wear resistance, corrosion resistance, good electrical insulation and high temperature stability. According to the different alumina content, it can be divided into different grades, such as 95 porcelain, 99 porcelain, etc., among which 99 porcelain refers to ceramic materials with an alumina content of 99%. As the alumina content increases, its mechanical strength and electrical insulation properties will also increase accordingly.

Characteristics of Alumina Ceramics
